I use Steemvoter for partly this purpose, and to support peers around the same level.
The 2nd account is for SP curation rewards.
SteemSQL is a bargain for me, I use it on a least two posts a week - one of those has just paid out the monthly subscription for the next four months 😁
I can see that for an established Data Analyst posting regularly like yourself it's probably not a big deal. But for someone doing a few ad-hocs and experimentation with no established data analysis interest amongst their following I think $70 US a month (up from $0) is a stretch, so it's a barrier to entry. Each to their own though, I will just focus on something else and maybe have another look when the SBD price comes down.
Fair enough.
I don't look at the cost in USD. If the price of SBDs come down to $1, I'd still make 3/4 times the monthly cost with a post.
More engaging posts like this one and you wont need to worry.
You could also hire a data analyst to do the work I guess? :)
